Getting RAW Video

[leegong]

Just found that there are several different kinds of source for LiveView intermedia product which
is fed to HDMI .
1) 12bits_1664x1088 source
2) 12bits_4928x2400 source
3) 12bits_4928x1400 source
Firmware activates 2) or 3) if dist_x10_ent.field_39E4.bit6:5 == 1 ,
dist_x10_ent.field_39E4 comes from struc_79.field_39F0 .
I even found 14bits 1664x1088 source setting for liveview at 0x241A00 .
The key point now is how to activate 2) or 3) , and change setting of chip4001 to get
12bits LV stream , firmware uses setting 1) now for normal Liveview , see code at 0x00121774 in the following screenshot .
EDIT : setting 2) , 3) are strongly related to sensor , EI155 task code , however still a mess to me .

Just wrote a patch to get RAW vdieo , if it works ,
each RAW video frame should be written as one file to SD card ,
based on my current decoding , the RAW video file probably is 1664 x 1088 12bits BAYER format ,
probably the RAW video data has not been processed with White Balance tuning , Color correction , gamma adjustment ...
Anybody wants to test the patch ?
Note :
I can not promise no risk of bricking , it's at your own risk .

Would love to test this patch

Can post videos comparing to 64mbps and also clean HDMI out to atomos recorder

Just loaded the patch and recorded a test video

Inspection shows the video was 8bit 22mbps .mov file

Did I need to have camera on a certain setting before recording?
I know the firmware updated because I was using the 64mbps patch

I will continue trying to locate the raw video
Thank you so much leegong and the nikon hacker team

Just load the patched firmware , then activate LiveView , no more actions are required .
If the patch works , it should generates lots of LV_?????.RAW files on SD card ,
do you get these files ?

I am not getting the raw live view files on my SD card

Tried on 2 d5100s and 3 different SD cards
